Answer : W = 450 J and P =  56.25 Watts

Explanation :

It is given that,

Force, F = 30 N

Distance, d = 15 m

Time, t = 8 sec

The work done is given as :

W = F.d

W=30\ N\times 15\ m

W = 450\ J

So, the work done to push a box across the floor is 450 N.

Mechanical power is defined as,

P=\dfrac{Work}{time}

P=\dfrac{450\ J}{8\ s}

P = 56.25 Watt

The power is 56.25 Watts.

Hence, this is the required solution.
